On the software page for mosh click on 'Show other versions' and if you're lucky the right SLES version will be available.

I recommend clicking on the first item (in case of SLES 11 SP3 that would be 'network') which leads you to the Open Build Service (OBS) page of mosh at OpenSUSE. There, select 'Download package' which leads you to yet another download page. There you can select your SLES version again and choose your preferred installation method: one click, zypper or direct download of the RPMs.

SLES and OpenSUSE are two very different species. SUSE is extremely concervative and has very limited package selection.

What follows may affect your SUSE support contract. SUSE support has repeatedly asked to remove any "foreign" packages, so if you follow instructions below, you might end up having a bad day when calling to SUSE support.

Some OpenSUSE packages will run happily on SLES without modification. What you can do is to enable an OpenSUSE repository for zypper and then try to install mosh from it, just to see if it works or not.

To get one of OpenSUSE repositories into zypper you create a file, /etc/zypp/repos.d/OpenSUSE-repositories.repo with following content:

When you've created the file, just run zypper ref OpenSUSE-11.4-OSS and then zypper search mosh.

This example uses OpenSUSE 11.4 and enables only one of the repositories, namely Open Source Software (OSS) repository. Adjust the version to match your SLES version as close as possible (going lower usually works, going higher will not).

I tried this on SLES11 SP2 and it was not able to find 'mosh'. Not to be confused with 'moss', which I do not instend to install. You say going lower in version will help. I am not able to find any lower version repo than 11.4.

As said, I'm not sure if mosh is even available from OpenSUSE repositories, that's what was left as an exercise for you. My apologies for that.
